[R] periodic function

I'm trying to built a model for a time-series analysis with an periodic term for seasonality.
I've tried both harmonic (package spatstat) and periodicSpline (package splines). The former don't allow a periodic constraint (or it does?), while I've not been able to use the latter within a dataframe with several repetition of the month series along the years.  

Can you suggest some options or new commands?  

Thanks a lot
